APPARATUS FOR PREPARING AND DISTRIBUTING OF AERATED DRINKS OR SIMILAR FLUIDS.

Specification of Letters Patent. 2 Patented N 13,1917,

Application filed May 9, 1917. Serial No. 157,439.

To, all whom it may concern Be itkno'wn that '1, Kim. Tam BOUVIN,

a subject of the King of Sweden, residing at Molndal, in the county'of 'Gottenborg and Bohus and Kingdom of Sweden, have invented new and useful Improvements in Apparatus'for Preparing and Distributing of Aerated Drinks or Similar Fluids, of which thefollowin'g is a specification.

This invention relatesto improvements in bottles or other containers for preparing and distributing aerated drinks such as mineral waters'charged with carbonic acid or the like. In previously known devices of this kind, the aerated drinks have lacked freshness and flavor, owing in large measure to the fact that the carbonic acid is too quickly freed from the water whenthe container is uncovered for distributing the aerated drink, or to the fact that the aerated drink is not prepared under a higheropressure than that of the atmosphere. A further disadvantage in connection with these prior devices is that the salts and acids from which the carbonic acidgas is to be de-' veloped must generally be employed in solid form, and so dissolve too slowly to permit preparation of a beverage for use on the instant.

The object of this invention is to provide a special apparatus including a receptacle or container within which an aerated drink may be prepared in a cheap and convenient way, exactly as and when wanted, under an excessive pressure above that of the atmosphere; the apparatus being particularly adapted for family usein households or on In carrying the invention into effect, there is provided a vessel or receptacle a, preferably of bottle shape and constructed of glass, china or the like. The receptacle a has a discharge opening 6 provided with a screwcap 0 or other suitable, readily-removable closure. If desired, the receptacle a may be "provided with a siphon 0 having a discharge pipe or nozzle '7, and a spring actuated valve (Z. N ear its bottom the receptacle a is provided with another opening 9 through whicha small vessel 72, can be insertedinto the receptacle a. -Opening 9 is surrounded by a" sleeve or apron 7c eXteriorly threaded so that a metal cap 2' may be screwed on the sleeve is to clamp in place a suitable washer Z of rubber or thelike to close the outer end of the small vessel it and the joint-between the small vessel and the receptacle a.

b The walls of the small vessel 72, mustbe adapted to allow the fluid in the receptacle to communicate with the contents of the small vessel, but at a rather slow rate. To this end'the walls of the vessel h are permeable.

The vessel may be'porous, such as would be the case with the vessel of ordinary nonglazed earthenware, or provided with perforations or small holes m, positioned near the outer end" of the vessel it for a purpose brought out below. The vessel h shown'in Fig. '2 will in some cases be found to increase the utility'of the apparatus, this vessel having a partition wall 0 dividing its interior into two chambers s and 25.

The invention also contemplates that the vessel It may be provided with two or more such partition VZL1].S for dividing 'the'interior of the vessel into a corresponding number of'chambers as desired.

It is not necessary that the cap 0 and vessel h be applied to the receptacle a in the relation shown in Fig. 1; for instance, the'cap and vessel may have their positions reversed, in which event, if desired, a discharge cock n or the like maybe substituted for the cap 0, as illustrated in Fig. 3. It will be understood that the shapes and materials of container a and vessel h are not essential to the invention, provided the shapes and ma terials selected are adequate to withstand "the gas pressures set up in the apparatus when in use.

When utilizing'the apparatus, the receplevel rises to the line A-A, the vessel It,

filled with the proper amount of water solution of the wine, lemon, or other selected acid, is passed through the opening 9 and seated in place therein as illustrated. When the vessel h is provided with one or more partition walls 0, each of the chambers s, t, etc., formed thereby, may be supplied with a particular acid.

When the permeable walls of the vessel h are of porous material, the material must be such that the contents of the vessel will not escape too rapidly into the receptacle a 7 but will be retained in the vessel until the vessel has been introduced into the receptacle and the screw cap 2' has been applied to clamp the vessel in place in a fluid tight manner by means of the washer Z. If the walls of the vessel h are of a non-porous material, the holes on must be positioned remote from the inner end of the vessel when inserted in the receptacle, so that the vessel may be supplied with and retain the necessary amount of acid solution before the vessel is clamped in place in the receptacle. Then the cap 71 is securely closed I the receptacle a is stood upright as shown in Fig. 1, and then the liquid contents of the receptacle a and the vessel 71, are per-' mitted to come into contact and mix by way of the pores of the walls of vessel It or of the holes m therein, so that carbonic acid gas is developed from the salt in the receptacle a, to charge the liquid in the receptacle, the liquid being flavored by the acid liberated from the vessel h. By this means the beverage being prepared may be flavored and aerated as desired to satisfy any particular taste; and the beverage is always fresh when distributed. If a siphon e is provided manual actuation of the valve d permits the pressure set up by the carbonic acid to discharge any desired quantity of the drink through the nozzle f; or the drink may be drawn off by uncovering the open ing 6.

The foregoing description of operation refers to the embodiment of Figs. 1 and 2. The arrangement of Fig. 3, which involves the provision of means for receiving the vessel it, including a screw cap a like that of Fig. l, at the top of the receptacle a when upright, and means for drawing off the charged drink, as a cock n, near the bottom of the receptacle, it will be understood that there is no need for tilting the receptacle a' 'when supplying the liquid to be charged or when inserting the vessel Z), as the liquid may be introduced by merely removing the cap 2' and vessel h after seeing to it that the cock n is closed. The receptacle a need not be tilted even after the cap i is screwed home and the vessel It clamped in place, if the walls of the vessel are sufficiently porous to tributing aerated drinks and the like, comprising a receptacle for a liquid to be charged having a distributing opening and a second opening remote therefrom, a small vessel adapted to be inserted through and seated in the second opening and adapted to contain ingredients to charge'the liquid when mixed therewith, the small vessel being open at one end and having permanent walls constructed to permit the slow passing of l1q-- uid therethrough to permit delayed communication between the liquid in the receptacle and the ingredients in the Small vessel, and means to secure the small vessel in the sec- 0nd opening in a fluid-tight manner and to close the open end of the small vessel in a fluid-tight manner.

2. An apparatus for preparing and distributing aerated drinks and the like, comprising a receptacle for a liquid to be charged having a distributing opening and a second opening remote therefrom, a small vessel adapted to be inserted through and seated in the second opening and adapted to contain ingredients to charge the liquid when mixed therewith, the small vessel having an opening in its outer end by which the contents of the vessel may be varied, means to secure the small vessel in place on the receptacle in a fluid-tight manner and to close Y the opening in the small vessels outer end in a fluid-tight manner, and a plurality of holes in the side Wallsof the small vessel adjacent to the outer end of the vessel and so positioned that the contents of the ves-' sel and receptacle may be mixed, after the vessel is secured in place on the receptacle, only by tilting the receptacle.

3. An apparatus for preparing and distributing aerated drinks or other fluids, comprising a receptacle for the fluid 'to be charged having a distributing opening as well as another opening remote from the distributing opening, a small vessel fitted into the receptacle in the last-mentioned to charge the same, the small vessel having In testimony whereof I have aflixed my permeable Walls and a partition 1Wallb disignature in presence of two Witnesses. vicling its interior into separate 01am ers and means to close the vessel and secure it KARL THURE BOUVIN' 5 on the receptacle in a fluid-tight manner to WVitnesses:

preclude escape of the contents of the ves- GUs'rAF GERTA, sel and receptacle from the latter. ALEX. FOQU'BERRY.
